Let's do this. I used this guy in one of my many incomplete Monotypes, but he was definitely useful!
Pokemon: Ambipom
Ability: Technician (or Pickup if you just want a Pickup slave)
Moveset: Fake Out, Last Resort OR Fake Out, Double Hit, Pursuit/Shadow Claw, Brick Break/Acrobatics OR Fake Out, Double Hit, Nasty Plot/Agility, Baton Pass
Ranking: B or A
Analysis: Ambipom sadly doesn't get too many of its great moves yet, but it is still very resourceful, especially with its wonderful Attack and Speed. First there's the classic Fake Out (STAB and Technician boosted) with Last Resort (Base 140 STAB), which is the "nuke option". If you don't like only having two moveslots filled, you can go for a set with more coverage, utilizing STAB and Technician boosted Fake Out and Double Hit, along with Technician boosted Pursuit and Acrobatics or just the decent Shadow Claw and Brick Break. If you feel that Ambipom's movepool is just too lacking, you can go for a Baton Pass set with Nasty Plot or Agility, to pass along to better Special attackers! Be careful, as Ambipom is fairly frail, but Ambipom has potential to be a very hard hitter or a speedy stat passer!
